Cleveland C96015 Spiral Point Tap
The Cleveland C96015 is a spiral point tap designed for creating unified fine threads in metalworking applications. It suits machinists and maintenance technicians who need reliable internal threading for fasteners.
1/4 Inch -28 UNF Thread Size
This tap cuts a 1/4 inch -28 UNF thread with a 2B class of fit and thread limit. The 5.45 mm drill size for 75 percent thread engagement determines whether this tool matches the required hole preparation.
Cobalt Construction With Hard Lube Coating
Cobalt material provides high heat resistance and wear life when tapping tough alloys. The Hard Lube coating reduces friction during cutting, while the spiral point design pushes chips ahead of the tap in through-hole operations.

Questions about this item
What does the 1/4-28 UNF thread size mean when I'm tapping a hole?
It cuts a 1/4 inch diameter thread with 28 threads per inch in Unified National Fine form, giving a finer pitch than coarse threads for stronger engagement in thinner material.
How does the Hard Lube coating affect tap life and chip flow?
The Hard Lube surface treatment reduces friction and improves chip evacuation, extending tool life when threading steel and stainless alloys.
What drill size do I need for a 75 percent thread depth with this tap?
Use a 5.45 mm drill to produce the recommended 75 percent thread engagement before tapping with this 1/4-28 UNF spiral point tap.
